Have you ever wished you could share information and interact with friends while visiting some of your favorite websites? There are a number of great social networking sites out there that let you stay connected, but the rest of the web typically hasn't been social. Yet.
Site owners have been saying for a while that they would love to provide this functionality, but, frankly, it's been too hard to add social features. A lot of code has to be written to create a site where visitors can sign up and bring their friends along, form new friendships, and do engaging things together. And not to mention that if you're a site visitor, it's pretty inconvenient to create a new account and try to rebuild a network of friends each time you visit a site.
Enter Google Friend Connect. This new service, announced as a preview release tonight at Campfire One, lets non-technical site owners sprinkle social features throughout their websites, so visitors will easily be able to join with their AOL, Google, OpenID, and Yahoo! credentials. You'll be able to see, invite, and interact with new friends or, using secure authorization APIs, with existing friends from social sites on the web like Facebook, Google Talk, hi5, LinkedIn, orkut, Plaxo, and others. And quite simply, you'll be able to do things together.
Having faces show up at a site is not enough. Friend Connect lets site owners include OpenSocial apps made by a world of developers. We're providing a few apps, such as posts and ratings, to get the ball rolling. And many more will be provided by the OpenSocial community.
With this functionality, there's no end to the possibilities. A small site dedicated to mountain biking in Moab, for example, would be able to have members who could exchange maps, tips, and pictures of their latest rides. A stroke victims support site could help grieving family members assist one another by sharing advice. A politician's site could enable supporters to advocate their viewpoints. A musician's site could give fans the chance to interact full tilt with the band and one another.
Take a look at a few white-listed sites using Google Friend Connect: Ingrid Michaelson's official website, which includes the iLike music application, and Bible Apps, owned by an OpenSocial developer fully dedicated to his "Verses" application -- where people can post prayers and test their knowledge of the Bible as a quiz game with their friends.
If you run a website and would like to add social features, you can now sign up for the wait list and learn more by visiting www.google.com/friendconnect. We're going to keep things pretty limited at first so we can gather feedback from site owners, developers, and users, but, in the weeks ahead, we'll be reaching out to more site owners and adding more social apps to the gallery.
You can also learn more about Google Friend Connect, OpenSocial, and other social initiatives at Google I/O, a two-day developer gathering about building the next generation of web applications. It takes place May 28-29 at Moscone West in San Francisco. Register now for Google I/O at http://code.google.com/events/io/.

How auctions set ad prices
All of the major search engines use auctions to price ads. The reason is simple: there are millions of keywords that need to be priced and it would be impossible to set all those prices by hand.
Using an auction removes the burden of having to do this: the prices are determined by the auction participants. These auctions run every time a user enters a query, so they always reflect the current values that advertisers place on keywords.
The outcome of the ad auction is efficient in the sense that the available ad slots are awarded to those who value them mostly highly. The outcome is also equitable in that the price an advertiser has to pay is determined by the other advertisers -- those with whom it has to compete for slots.
But how do they actually work? There are several steps in the process.
1) Each advertiser enters a list of keywords, ads, and bids.
2) When a user enters a query, Google compiles a list of all the ads whose keywords match that query.
3) The list of ads is then ordered based on the bids and the Ad Quality Scores, which measure the relevance of the ad to the user.
4) The highest ranked ad is displayed in the most prominent position, the second highest ranked ad gets the second most prominent position, and so on.
5) If the user clicks on an ad, the advertiser is charged a price that depends on the bid and Quality Score of the advertiser below it. The price charged is the minimum necessary to retain the advertiser's position in the list.
A simple example is when all ads have the same Quality Score. In this case, the ads will be ranked by bids and the price an advertiser pays per click will just be the bid of advertiser below it in the ranking. Hence the amount that advertisers pay is no more than what they bid and typically less.
In the general case, where ad qualities differ, the price an advertiser pays for a click will depend on its Quality Score relative to the quality of the ad below it in the auction. Roughly speaking, an ad that has twice the quality of another ad will tend to get about twice as many clicks, and will only have to pay half as much per click as the competing ad.
Where does this Ad Quality Score come from? It was originally determined by historical click through rates but has been refined over the years using sophisticated statistical models. Using ad quality as a factor in ranking ads provides strong incentives to advertisers to make sure that they provide relevant ads to end users.
There are many additional tweaks on top of this basic design. For example, Google actually runs two auctions: one for ads at the top of the page, and one for ads on the side of the page. Only ads with particularly high quality are eligible to compete in the top-ad auction. Ads that have particularly low quality may be disabled, and not shown at all. Advertisers also can set and adjust their daily and monthly budget so as to cap their maximum spend.
But the essential structure is that outlined above: advertisers bid for position and pay just enough to beat their runner-up. Prices for keywords are, ultimately, determined by the advertisers.

Your vote matters
A couple of months ago, we announced the Doodle 4 Google art competition and invited students in grades K-12 across the U.S. to redesign our logo around the theme "What if...?".
Since then, more than 16,000 kids across the country have been busy creating their doodles. It's been a lot of fun for us and the kids.
Today we're excited to announce the state finalists and 40 regional winners. The thousands of wonderful entries made judging difficult, but with the help of experts at Young Audiences, Teach for America and reporters from across the country, we've managed to narrow the field to the very best.
Now it's your turn. Starting today, you can vote for your favorite doodle. Your votes will determine the four national finalists. Just make sure to vote soon: you only have until May 18th. The national winner will be announced and the winning doodle will replace our usual logo on the Google homepage on May 22nd.

Growing our connection to food
Today at our Mountain View headquarters we're celebrating the one-year anniversary of an important project: our organic garden. Not only does it provide a stunning centerpiece for the central campus; it yields produce and herbs that are used daily in the cafes on campus. Although many Googlers would like to think of themselves as Renaissance men and women, a green thumb didn't exactly come as easily to some as C++ development might. Fortunately, the garden wasn't just an ambitious 20% project but rather, an initiative that we took on with the partnership of The Growing Connection.
The Growing Connection is a grassroots project of the UN's Food and Agriculture Organization (FAO). The work of the Growing Connection originates with a humble earth box, a patented growing system that helps growers to cultivate produce with limited space and water. The project really has two parts: teaching people around the world, especially kids, how to cultivate their own food, and giving them a hands-on lesson in nutrition. The latter entails connecting growers so that kids growing corn on rooftops in Harlem can share their experiences with students planting earth boxes in Ghana.
To earmark today's anniversary, we had a little get-together at the Googleplex, complete with cucumber and lemon verbena infused waters, organic snacks and a few words from Robert Patterson, Senior Liaison Officer at FAO. "Like Google, Growing Connections combines growth and information," he observes. "So coming to Google has been a natural fit. We work from kids from all over--Africa, Latin America, the Caribbean and the United States. They learn to like each other through food and realize that they're part of an actual solution for hunger and poverty."

OSO conference takes the cake
Last week at the annual meeting of our Online Sales and Operations (OSO) organization, a group of us (1,211 Googlers from around the world, to be exact) made an attempt to set a new Guinness World Record for the "largest cake decorating lesson." This isn't the first time we've taken our culinary talents to great heights, but it is the first time we've attempted to bake our way to a new record.
The event brought our teams together, united around something we all love: good food. We decorated a total of 171 cakes, using 800 pounds of butter cream and 500 pounds of fondant along the way. In addition to this fun foray into the sugar arts, the two-day conference featured a keynote speech by Al Gore, workshops with faculty from the Harvard Business School, and several panels on industry trends, including one on bloggers moderated by Kara Swisher.
